I am working for an IS OIL Client and we have a client requriement.
We have a External Fields Tab under Item details in STO(Stock Transport Order). In this tab, we have "Mode of Transport" field which is a drop down kind of field. Upon clicking F4, we can display the list of options and we can select the appropriate answer from it. Now the client requirement is to make this Mode of transport field Mandatory. I searched a lot in standard SAP configuration but cannot find any option to make the field mandatory.
Anyone who have an idea, Please help.
